In the early episodes the Tazelwurm appeared to be nothing more than a vicious, carnivorous predator. It was often seen attacking students, including Lee, and apparently trying to eat them. However, this was intended mainly to serve as a means to scare them. In reality, the Tazelwurm is highly intelligent, at least comparable to a human level intelligence. Further, he has proven himself a valuable ally to Lee, providing him with vital information about The Prank and saving him from getting caught on several occasions.
